Q: Should you run a dehumidifier in the basement all the time?

• <div><p>No, your basement dehumidifier doesn&rsquo;t need to be on 24/7. While it&rsquo;s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.</p></div>

Q: How long does foundation sealant last?

• <div><p>You&rsquo;ll need to reseal the foundation <b>every five to 10 years, </b>depending on the sealant you&rsquo;ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.</p></div>

Q: Do all basements eventually flood?

• <div><p>Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn&rsquo;t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a <a href="https://www.angi.com/articles/flood-wall-around-house.htm">flood wall around the house</a> if you live in a flood-prone area.</p></div>

Q: What is the best type of insulation for crawl spaces?

• <div><p>Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.</p></div>
